This application claims priority to European Patent Application No. 10305512.5, filed May 14, 2010, entitled 'SYSTEM AND METHOD FOR MOBILE COMMUNICATIONS'. The contents of this patent application are incorporated herein by reference in their entirety.

Technical field

The present invention relates to a system and method for mobile communication.

Data transmission rates of mobile devices have increased in part with the development of networks. One such development is Enhanced Data Rates for GSM Evolution (EDGE), also known as Enhanced GPRS (EGPRS). This is an backward-compatible digital mobile phone technology that extends beyond the standard global mobile communication system (GSM) and improves data transmission rates.

As another upgrade to GSM and EDGE, the introduction of EDGE evolution or Evolved EDGE will further increase the data transmission rate. One such feature of the evolved EDGE is the Downlink Dual Carrier (DLDC), which allows the mobile device to simultaneously receive data on two different frequency channels, doubling the downlink throughput.

Disclosed herein are systems and methods for mobile communication. An exemplary mobile station, in operation, causes the mobile station to receive first data from a carrier at a first frequency using a first receiver of the mobile station in a first timeslot, wherein the first receiver is configured to receive first data during the first timeslot. Tune a second frequency of the carrier using a second receiver while receiving and receive second data from the carrier at a second frequency using the second receiver during a second timeslot immediately following the first timeslot. And software and hardware stored on tangible computer readable media.

The exemplary mobile station described herein, during operation, causes the mobile station to receive first data from a carrier at a first frequency using a first receiver of the mobile station in one timeslot, and during the timeslot, Tune a second frequency of the carrier using a second receiver while receiving the first data, and second data from the carrier on the second frequency using the second receiver during another timeslot immediately following the timeslot. Hardware and software stored on a tangible computer readable medium for receiving the data.

In some implementations, hardware and software cause the mobile station to receive data in all timeslots within each frame of two consecutive time division multiple access frames, and the frequencies of each of the two time division multiple access frames are different. In some implementations of the mobile station, the hardware and software also cause the mobile station to simultaneously perform neighbor cell measurements using the second receiver while the first receiver receives the first data. In some such implementations, neighbor cell measurements are performed during timeslots of time division multiple access frames.

In some implementations of the mobile station, the hardware and software also cause the mobile station to transmit an indication to the carrier that the mobile station supports high speed downlink frequency switching. In some implementations, the carrier uses frequency hopping. In some implementations, the hardware and software also cause the mobile station to tune the carrier's third frequency using the first receiver while the second receiver receives the second data during another timeslot.

Another exemplary mobile station includes hardware and software stored on a tangible computer readable medium that, during operation, cause the mobile station to establish a communication session with the communication network and transmit mobile station capability information elements to the network. The mobile station capability information element includes an element indicating multislot reduction of dual carrier operation for enhanced flexible timeslot assignment. In some implementations, the factor indicative of multislot reduction in dual carrier operation for enhanced flexible timeslot allocation is reduced flexible timeslot allocation multislot capability of the downlink dual carrier information element. In some implementations, the dual carrier operation is a downlink dual carrier operation.

In some implementations, the mobile station capability information element also includes a second element indicating multislot reduction of dual carrier operation for non-enhanced flexible timeslot allocation operation. In some implementations of the mobile station, the hardware and software allow the mobile station to calculate an element that indicates multislot reduction of dual carrier operation for enhanced flexible timeslot allocation operation.

In some such implementations, the hardware and software allow the mobile station to determine the maximum number of receive timeslots for the signaled multislot class of the mobile station and to determine the number of receive timeslots supported by the mobile station during enhanced flexible timeslot allocation. Determine the maximum number and subtract the maximum number of receive timeslots supported by the mobile station during the enhanced flexible timeslot assignment from the maximum number of receive timeslots for the signaled multislot class of the mobile station. By determining the multislot reduction of the dual carrier operation for the device, the factor indicating the multislot reduction of the dual carrier operation for enhanced flexible timeslot allocation is calculated.

In another implementation, the hardware and software allow the mobile station to determine the maximum number of receive timeslots for the mobile station's alternative enhanced flexible timeslot assignment multislot class, and during the enhanced flexible timeslot assignment. Determine the maximum number of receive timeslots supported by the receiver, and determine the maximum number of receive timeslots supported by the mobile station during the enhanced flexible timeslot assignment. Subtracting from the maximum number of slots determines the multislot reduction of the dual carrier operation for enhanced flexible timeslot allocation, thereby calculating the factor indicative of the multislot reduction of the dual carrier operation for enhanced flexible timeslot allocation.

In another implementation, the hardware and software may cause the mobile station to determine the maximum number of receive timeslots for the mobile station's generally enhanced flexible timeslot assignment multislot class and receive times for the signaled multislot classes of the mobile station. Determine the maximum number of slots, determine the maximum number of receive timeslots supported by the mobile station, determine the maximum number of receive timeslots supported by the mobile station during enhanced flexible timeslot allocation, and The maximum number of receive timeslots is subtracted from the maximum number of receive timeslots for the signaled multislot class of the mobile station to determine a decrease value, and the receive timeslots supported by the mobile station during the decrease value and enhanced flexible timeslot allocation. The maximum number of mobile stations to be replaced by the enhanced flexible timeslots Subtract the multislot reduction of dual carrier operation for enhanced flexible timeslot allocation by determining the multislot reduction of dual carrier operation for enhanced flexible timeslot allocation by subtracting from the maximum number of receive timeslots per multislot class per Allows you to calculate the element to display.

In some implementations of the mobile station, the hardware and software can also cause the mobile station to receive enhanced flexible times when the mobile station can receive fewer receive timeslots than the maximum number of receive timeslots for the signaled multislot class of the mobile station. The element indicating multislot reduction of dual carrier operation for slot allocation is omitted from the mobile station capability information element. In some implementations, the hardware and software can also cause the mobile station to perform enhanced flexible timeslot assignment when the mobile station can receive the maximum number of receive timeslots for the mobile station's alternate enhanced flexible timeslot allocation class. Omitting from the mobile station capability information element an element indicating multislot reduction of the dual carrier operation for include the multislot reduction of the downlink dual carrier value reserved for future use.

Also disclosed are methods and apparatus for implementing various implementations of a mobile station.

Referring to FIG. 1, a mobile device 10 (eg, mobile station MS) is shown communicating with a wireless base station 12. Mobile device 10 may exchange data communication with another entity via one or more base stations 12 of a wireless network. The exchange of wireless data is shown in dashed lines.

Mobile device 10 may utilize radio receiver equipment 14, 16. The radio receiver equipment 14, 16 may share some receiver components. Alternatively, the radio receiver equipment 14, 16 may be two independent radio receivers. In the example shown, the radio receiver equipment 14, 16 is labeled 'R1' and 'R2', respectively. The radio receiver equipment 14, 16 allows the mobile device 10 to simultaneously receive data at different frequencies, simultaneously tune two different frequencies, perform neighbor cell measurements, and / or perform any combination of the above procedures. It can be done. For example, in a network supporting downlink dual carrier (DLDC), the mobile device 10 supporting DLDC may receive data simultaneously on two carriers (frequency). Alternatively, as described in more detail herein, when the mobile device 10 including the dual radio receiver equipment 14, 16 communicates with a single carrier system, the mobile device 10 is equipped with the dual radio receiver equipment. (14, 16) can be used to increase the communication rate in the presence of a frequency hopping network. For example, when base station 12 uses frequency hopping in a time division multiple access (TDMA) frame for one or more carriers, radio receiver equipment 14 may be used to receive data, and the downlink carrier may use frequency. Prior to hopping, the radio receiver equipment 16 may tune to the next frequency to prepare the radio receiver equipment 16 to receive data during the next frame reception. The second receiver may further perform neighbor cell measurement or base station identification code (BSIC) decoding behavior before receiving data in the next TDMA frame. Thus, the switching time defined for the mobile multislot class can be reduced to zero or nearly zero when frequency hopping is used to enable eight downlink slots per TDMA communication frame. During the next frame, the duties of the dual radio receiver equipment 14, 16 are reversed.

When mobile device 10 operates in DLDC mode with a network, the amount of data received and therefore the amount of data that must be processed by mobile device 10 is increased. Thus, although the communication system of the mobile device 10 may receive communication in a predetermined number (eg, 16) timeslots per TDMA frame, the processing system of the mobile device 10 processes the data in a timely manner. You may not be able to. Thus, as described in greater detail below, mobile device 10 may signal to the network that a reduced number of slots should be used when operating in DLDC mode.

In the example shown, at least one of the radio receiver equipment 14, 16 includes a transmitter that enables the mobile device 10 to transmit data. In other embodiments, each radio receiver equipment 14, 16 includes both a receiver and a transmitter, or a transceiver. In this way, it can be expected that mobile device 10 can simultaneously transmit and receive at different frequencies.

Mobile device 10 may be a bidirectional communication device having advanced data communication capabilities, including the ability to communicate with other mobile devices 10 or computer systems via a network of transceiver stations. Mobile device 10 may also have voice communication capabilities. Depending on the capabilities provided by mobile device 10, mobile device 10 may be a data messaging device, a two-way pager, a cellular telephone with data messaging capability, a wireless Internet device, or a data communication device (with or without telephone functionality). Can be called. Mobile device 10 may also be used in a system configured to continuously route all forms of pushed information from a host system to mobile device 10.

An exemplary configuration of mobile device 10 is shown in FIG. 2 shows a block diagram of an exemplary embodiment of a mobile device 10. Mobile device 10 includes a number of components, such as main processor 102, which controls the overall operation of mobile device 10. Communication functions, including data communication and voice communication, are performed through communication subsystem 104. Communication subsystem 104 receives data from and transmits data to wireless network 20. In this exemplary embodiment of the mobile device 10, the communication subsystem 104 is configured in accordance with the GSM and GPRS standards used worldwide. Other communication configurations that may be equally applicable are, for example, the evolved EDGE or EDGE evolution mentioned above. Although new standards are still being defined, it is believed that the new standards will have similarities to the network behavior described herein, and those skilled in the art will appreciate that the embodiments described herein may employ any other suitable standard to be developed in the future. It will be understood that it is intended to be used. The wireless link connecting the communication subsystem 104 with the wireless network 20 represents one or more other radio frequency (RF) channels operating in accordance with defined protocols specified for GSM / GPRS communication.

Main processor 102 includes random access memory (RAM) 106, flash memory 108, display 110, auxiliary input / output (I / O) subsystem 112, data port 114, keyboard ( It also interacts with additional subsystems such as 116, speaker 118, microphone 120, GPS receiver 121, short range communication 122, and other device subsystem 124. As described below, short-range communication 122 may implement any suitable device-to-device or peer-to-peer communication protocol capable of communicating directly over a relatively short distance, for example, from one device to another. . Examples include Bluetooth®, ad hoc WiFi, infrared, or any "long-range" protocol reconfigured to use short-range components available. Therefore, it will be understood that short-range communication 122 may represent any hardware, software, or combination thereof that allows a communication protocol to be implemented between devices or entities within a short-range scenario, whether the protocol is standard or private.

Some subsystems of the mobile device 10 may perform communication related functions, while other subsystems may provide "resident" or on-device functionality. For example, display 110 and keyboard 116 may be used for both communication-related functions such as text message input for transmission over network 20 and device-resident functions such as calculators or task lists.

The mobile device 10 may transmit and receive a communication signal via the wireless network 20 after the necessary network registration or activation procedure is completed. Network access is associated with a subscriber or user of the mobile device 10. To identify the subscriber, mobile device 10 may use a subscriber module component or “smart card” 126 such as a subscriber identification module (SIM), a removable user identification module (RUIM), and a universal subscriber identification module (USIM). have. In the example shown, the SIM / RUIM / USIM 126 must be inserted into the SIM / RUIM / USIM interface 128 for communication with the network. Without the components of the SIM / RUIM / USIM 126, the mobile device 10 may not perform sufficient operation to communicate with the wireless network 20. When the SIM / RUIM / USIM 126 is inserted into the SIM / RUIM / USIM interface 128, the SIM / RUIM / USIM 126 is coupled to the main processor 102.

Mobile device 10 is typically a battery powered device and in this example includes a battery interface 132 for receiving one or more rechargeable batteries 130. In at least some embodiments, the battery 130 may be a smart battery with an embedded microprocessor. Battery interface 132 is coupled to a regulator (not shown) that allows battery 130 to provide V + power to mobile device 10. Although current technology uses batteries, it is also possible to power the mobile device 10 by future technologies such as micro fuel cells.

Mobile device 10 also includes an operating system 134 and software components 136-146 described in greater detail below. Operating system 134 and software components 136-146 executed by main processor 102 are typically stored in permanent storage, such as flash memory 108, which is alternatively read out. It may be a dedicated memory (ROM) or similar storage element (not shown). Persons skilled in the art may find that portions of operating system 134 and software components 136-146, such as special device applications or portions thereof, may be temporarily loaded into volatile storage, such as RAM 106. I will understand that. As is well known to those skilled in the art, other software components may also be included.

A subset of software applications 136 that control basic device operation, including data and voice communication applications, may be installed on mobile device 10 during manufacture of mobile device 100. The software application includes a message application 138, a device status module 140, a personal information manager (PIM) 142, a connection module 144 and an IT policy module 146, a high speed downlink frequency switching module 148, and DLDC reduction signal module 150 may be included. The message application 138 can be any suitable software program that allows a user of the mobile device 10 to send and receive electronic messages, which message typically resides in the flash memory 108 of the mobile device 10. Stored. Device status module 140 provides permanence. That is, device status module 140 ensures that important data of the device is stored in permanent memory, such as flash memory 108, so that data is not lost even when mobile device 10 is turned off or loses power. PIM 142 includes functions for organizing and managing data items of interest to users, such as but not limited to email, text messages, instant messages, contacts, calendar events, and voice mail. 20). The connection module 144 implements a wireless infrastructure, such as an enterprise system that the mobile device 10 is authorized to interface with, and a communication protocol required for the mobile device 10 to communicate with any host system 25. The IT policy module 146 is responsible for receiving IT policy data that encodes the IT policy and organizing and adhering to rules such as the "Set Maximum Password Attempts" IT policy.

The high speed downlink frequency switching module 148 of the illustrated example controls the operation of the communication subsystem 104 such that the mobile device 100 has a plurality of receivers (e.g., a single carrier with frequency hopping to reduce switching time). , Dual radio receiver equipment 14, 16 shown in FIG. In particular, when there are two receivers (e.g., in a DLDC capable mobile device), the exemplary fast downlink frequency switching module 148 is configured to an upcoming frequency that will soon occur after the second receiver performs neighbor cell measurements. While the first receiver receives data at the current frequency, for example, when no neighbor cell measurements are needed. Alternatively, the high speed downlink frequency switching module 148 may cause the second receiver to tune to an upcoming frequency without performing neighbor cell measurements. Thus, when the network hops to an upcoming frequency, the mobile device 100 can immediately receive data using the second receiver without waiting for the first receiver to tune to the new frequency. Subsequently, the first receiver can prepare for the next hopping and the circulation continues. An example process for implementing the fast downlink frequency switching module 148 is described in conjunction with the flowchart of FIG. 3.

The DLDC reduction signal module 150 of the illustrated example signals the reduction of the timeslot value for the mobile device 100 to the network. The decrease in the timeslot value is due to the receipt of additional timeslots (ie, reception of the maximum number of timeslots (e.g. twice the number of timeslots) using each receiver) during DLDC mode operation. It is used to signal the reduced capability of. The decrease in timeslot value is the number by which the maximum number of timeslots for the associated multislot class should be reduced to determine the timeslot capability of the mobile device 100. For example, the mobile device 100 may support up to eight timeslots per frame per receiver and the mobile device 100 uses two receivers to have 16 timeslots, which is the theoretical maximum per frame. When the assigned multislot class indicates, the DLDC reduction signal module 150 can only handle 12 (16-4 = 12) timeslots per frame (due to decoding or processing overhead). It can be determined that the decrease in the timeslot value is four. The DLDC reduction signal module 150 of the illustrated example transmits a first decrease in timeslot values for the non-EFTA mode of operation of the mobile device and a second decrease in timeslot values for the EFTA mode of operation of the mobile device, thereby transmitting the mobile device. Since the capabilities of 100 may differ in each mode of operation, provide an indication of the capabilities of the mobile device 100 in each mode of operation to the network. An example process for implementing the DLDC reduction signal module 150 is described in conjunction with FIG. 5.

Other types of software applications or components 139 may also be installed on the mobile device 10. This software application 139 may be a pre-installed application (ie other than the message application 138) or a third party application added after the mobile device 10 is manufactured. Examples of third party applications include games, calculators, utilities, and the like. Additional applications 139 may include at least one of wireless network 20, auxiliary I / O subsystem 112, data port 114, short-range communications subsystem 122, or any other suitable device subsystem 124. It can be loaded into the mobile device 10 through one.

Data port 114 may be any suitable port that enables data communication between mobile device 100 and another computing device. The data port 114 can be a serial port or a parallel port. In some examples, data port 114 may be a USB port including a data line for data transmission and a supply line capable of supplying charging current to charge battery 130 of mobile device 100.

For voice communication, the received signal is output to the speaker 118 and the transmit signal is generated by the microphone 120. Although the audio or audio signal output is primarily achieved through the speaker 118, the display 110 may also provide additional information such as the identity of the other party, the duration of the voice call, or other voice call related information. Can be.

To construct a data item, such as an email message, for example, a user or subscriber may have touch sensitive overlay 34 on display 32 that is part of touch screen display 28, perhaps in addition to auxiliary I / O subsystem 112. Can be used. The secondary I / O subsystem 112 may include a device such as a mouse, trackball, infrared fingerprint detector, or roller wheel with dynamic button press capability.

Flowcharts illustrating example processes that may be executed by the mobile station 100 are shown in FIGS. 3 and 5. In these examples, the process depicted in each of the flow diagrams may include (a) a processor such as main processor 102 shown in the exemplary mobile device 100 of FIG. 2, (b) a controller, and / or (c) a digital signal processor ( And one or more programs, including machine readable instructions, executed by any other suitable device, such as a DSP. One or more programs may be realized as software stored on tangible media, such as, for example, flash memory, CD-ROM, floppy disk, hard drive, DVD, or memory associated with main processor 102, but the entire program and / or program Some of which are alternatively executed by a device other than the main processor 102, and / or may be firmware or dedicated hardware (eg, special purpose integrated circuits (ASICs), programmable logic devices (PLDs), field programmable logic). Device (FPLD), implemented by discrete logic and the like).

For example, some or all of the fast downlink frequency switching module 148 and the DLDC reduction signal module 150, or any of the functions shown in FIG. 1 in connection therewith, may be implemented by any combination of software, hardware, and / or firmware. Can be implemented. In addition, some or all of the processes depicted in the flow charts in FIGS. 3 and 5 may be implemented manually. In addition, although the example process is described in connection with the flowcharts shown in FIGS. 3 and 5, many other techniques for implementing the example methods and apparatus described herein may alternatively be used. For example, with respect to the flowcharts shown in FIGS. 3 and 5, the order of execution of the blocks may be changed, and / or some of the blocks shown may be changed, removed, combined, and / or subdivided into a plurality of blocks. .

3 is a flow diagram illustrating an example process that may be used to implement the high speed downlink frequency switching module 148 of FIG. 2. The example flow diagram of FIG. 3 begins when the first receiver of the communication subsystem 104 of the mobile device 100 receives data from the network at a first tuning frequency (block 302). According to the example shown, the mobile device 100 supports DLDC, but the network operates in a single carrier frequency hopping mode, so the dual receiver capability of the mobile device 100 can be used with the single carrier mode. While the first receiver of the mobile device 100 receives data, the fast downlink frequency switching module 148 causes the second receiver to perform neighbor cell measurements (block 304). For example, the second receiver may perform neighbor cell measurement just before frequency hopping occurs with sufficient time for the second receiver to complete the neighbor cell measurement and tune to the next frequency.

After neighbor cell measurement is complete (block 304), the fast downlink frequency switching module 148 causes the second receiver to tune to the next frequency that the network hops (block 306). For example, the frequency hopping scheme of the network may be known to the mobile device 100 by one or more of a lookup table, a predefined equation that determines the next frequency, communication of frequencies from the network, and the like. When the second receiver is tuned (block 306) and the network hops to the next frequency, the second receiver begins to receive data at the tuned frequency (block 308). Thus, there is little or no need to adjust the delay to be accommodated between receiving data at both frequency hopping. Thus, even when frequency hopping is used in the network, the mobile device 100 can support the maximum number of receive timeslots (eg, eight timeslots per TDMA frame) in each TDMA frame.

While the second receiver is receiving data (block 308), the fast downlink frequency switching module 148 causes the first receiver to perform neighbor cell measurements (block 310) and tune to the next frequency to prepare for frequency hopping. (Block 312). Thus, the mobile device 100 alternately cycles between the first receiver and the second receiver.

Although the flowchart of FIG. 3 shows a process performed sequentially, the process shown in FIG. 3 may be performed in parallel. For example, at the same time as the first receiver receives data at the tuning frequency (block 302), the second receiver tunes to the neighbor cell measurement frequency, performs neighbor cell measurement (block 304), and / or to the next frequency. One or more of the tunings (block 306) may be performed. Similarly, while the second receiver receives data at the next frequency (block 308), the first receiver tunes to the neighbor cell measurement frequency, performs neighbor cell measurement (block 310), and / or tunes to the next frequency (block 312) may be performed. Alternatively, any other configuration and timing of the blocks can be used. For example, some blocks may be performed in series and some blocks may be performed in parallel.

Additional blocks may be included in the process shown in FIG. 3. For example, the fast downlink frequency switching module 148 may further signal to the network that the mobile device 100 supports fast downlink frequency switching. For example, the fast downlink frequency switching module 148 may send an MS radio accessibility information element to the network, including the fast downlink frequency switching capability bits, as shown below for 3GPP TS 24.008.

3 GPP TS  24.008 MS  Example Fields Contained in a Radio Accessibility Information Element

Alternatively, the high speed downlink frequency switching module 148 may alternatively signal the ability to receive the maximum number of timeslots. For example, high speed downlink frequency switching module 148 may assign that an alternative EFTA class applies to single carrier operation but not to DLDC, and high speed downlink frequency switching module 148 may have a maximum number of times. Indicates that slots can be used and also that the maximum number of timeslots can be used on a single carrier, but multiple timeslots reduced by DLDC reduction for EFTA indicate DLDC reduction for EFTA so that dual carrier operation can be used. Alternatively, alternative EFTA classes may be defined such that the maximum number of receive timeslots is mapped to a reduced number of receive timeslots per carrier of the DLDC configuration. The method described herein may apply to all DLDC situations, or only when frequency hopping is used for at least one carrier or for each carrier. For example, if one carrier uses frequency hopping and the other does not, the mobile device 100 supports the maximum number of timeslots (e.g. 8 receive timeslots) in the non-hopping carrier. It can support fewer timeslots (eg seven receive timeslots) in the hopping carrier.

4 is a diagram illustrating a reception relationship between an exemplary first receiver 402 and a second receiver 404 (eg, receivers of the communication subsystem 104 of the mobile device 100). According to the example shown, the first receiver 402 receives data during the first time period 406. During a second time period 408 that at least partially overlaps the first time period 406, the second receiver 404 performs neighbor cell measurements and tunes to the next frequency that the network hops. The first time period 406 ends when the network hops to a new frequency. When the network hops to the new frequency, the second receiver starts receiving data during the time period 410. As shown in the illustrated example, since the second receiver performs and tunes neighbor cell measurements during the time period 406, when the time period 406 terminates, the second receiver 410 receives data immediately or almost immediately. To start.

By way of example, Table 1 shows that some implementations of the systems and methods described herein include a mobile device 100 (eg, capable of receiving up to eight timeslots within a single TDMA frame on a single radio frequency channel). It is shown that a parameter reflecting the time required to perform adjacent cell signal level measurements and prepare to receive data can be set to zero even when the network uses frequency hopping. Table 1 is adapted from 3GPP TS 45.002. In the table, Rx represents the maximum number of receive timeslots that the MS can use per TDMA frame, Tx represents the maximum number of transmit timeslots that the MS can use per TDMA frame, and Sum represents the actual number of MSs per TDMA frame. The total number of uplink (u) and downlink (d) TSs that can be used, T _ta is related to the time required for the MS to perform neighbor cell signal level measurements and to prepare for transmission, and T _tb is the MS T _ra is related to the time required for the MS to perform neighbor cell signal level measurements and prepares to receive, and T _rb is the time required for the MS to prepare to receive data. Has a relationship with Similar implementations may apply to other multislot class mobile stations capable of receiving less than eight timeslots.

T _rb reflects the effective switching time when no measurement is performed, while T _ra reflects the time required for the MS to perform adjacent cell signal level measurements and prepare for reception. According to the current standard, mobile stations are not expected to perform neighbor cell signal level measurements when assigning or assigning some multislot configurations by the network (eg, T _rb instead of T _ra ). Also, BSIC decoding may not be possible for some other multislot configurations. However, as described above, in accordance with the systems and methods described herein, neighbor cell measurement and / or BSIC decoding and / or tuning is performed at the second receiver in parallel with receiving data at the first receiver. Thus, regardless of the value or applicability of the T _ra parameter for the relevant multislot configuration, neighbor cell measurement and / or BSIC decoding and / or neighbor cell measurement tuning is performed at the first receiver in accordance with Note 1 and Note 2 in Table 2. Can be performed in the second receiver in parallel with the reception of the data, while a maximum number of receive timeslots are available (e.g., eight receive timeslots per TDMA frame).

5 is a flow diagram illustrating an example process for implementing the DLDC reduction signal module 150 of FIG. 2. The example flow diagram of FIG. 5 begins when the mobile device 100 establishes a connection with a communication network (block 502). For example, mobile device 100 may send a mobility management attach (ATTACH) request to the network and respond with an ACCEPT response. Alternatively, any of several processes may be performed by mobile device 100 until sometime mobile device 100 communicates the capabilities of mobile device 100 to the network. DLDC reduction signal module 150 then causes mobile device 100 to determine the maximum number of receive timeslots (denoted here by X) for the signaled multislot class (block 504). For example, Table 3 shows that the maximum number of downlink timeslots is 10 when the mobile device declares a signaled multislot class 33. DLDC reduction signal module 150 then determines the maximum number of receive timeslots (indicated by Y) supported by the device (block 506). For example, the DLDC reduction signal module 150 may have 8 processing timeslots for the processing capability of the mobile device 100 even though the maximum number of downlink timeslots for the signaled multislot class 33 is 10. You can decide to limit the device to processing.

DLDC reduction signal module 150 then determines whether an alternative EFTA multislot class has been signaled or should be signaled (block 508). When an alternative EFTA multislot class is signaled or must be signaled, DLDC reduction signal module 150 determines the maximum number of receive timeslots (denoted A) of the alternative multislot class for EFTA (block 510). Alternatively, when the alternate EFTA multislot class is not signaled, the DLDC reduction signaling module 150 determines the maximum number of reception timeslots of the signaled multislot class (denoted by A) (block 512) Using the value determined at block 504). DLDC reduction signal module 150 then determines the maximum number of receive timeslots (denoted B) supported by mobile device 100 during the EFTA operation (block 514). In another implementation, block 514 may directly follow block 510 without following block 512, and control may then proceed to block 516. In such an implementation, block 518 is not performed when the alternative EFTA multislot class is not signaled, and control may proceed to block 516 instead.

DLDC reduction signal module 150 then calculates a non-EFTA reduction value by subtracting Y from X (block 516). In other words, DLDC reduction signal module 150 determines the non-EFTA reduction value by subtracting the maximum number of reception timeslots supported by the device from the maximum number of reception timeslots for the signaled multislot class.

DLDC reduction signal module 150 then determines the EFTA reduction value based on the value determined in one or more of blocks 504-514. For example, DLDC reduction signal module 150 may determine the EFTA reduction value by subtracting B from A (block 518A). In other words, DLDC reduction signal module 150 may determine the EFTA reduction value by subtracting the maximum number of receive timeslots for the device during the EFTA operation from the maximum timeslots for the alternative EFTA multislot class. Alternatively, DLDC reduction signal module 150 may determine the EFTA reduction value by calculating A- (X-Y) -B. In other words, the DLDC reduction signal module 150 subtracts the non-EFTA reduction value and the maximum number of receive timeslots for the device during the EFTA operation from the maximum number of receive timeslots for the alternative EFTA multislot class. Can be determined.

After calculating the non-EFTA reduction value (block 516) and the EFTA reduction value (block 518), the DLDC reduction signal module 150 causes the mobile device 100 to display the MS radio including the non-EFTA reduction value and the EFTA reduction value. Send accessibility information to the network (block 520). Alternatively, any other type of information element and message can be used. Thus, the network element may determine the capability of the mobile device 100 using the non-EFTA reduction value and the EFTA reduction value, for example by subtracting the reduction value from the maximum of the signaled class defined in 3GPP TS 45.002. .

For example, an example information element for sending an EFTA reduction value to the network is shown below based on 3GPP TS 24.008. This information element is provided by way of example, and other implementations may be used.

The DLDC reduction signal module 150 may alternatively signal the network to the network with a reduced reception capability for EFTA using a combination of non-EFTA reduction values and EFTA reduction values. Exemplary embodiments are shown in Table 4. The values in Table 4 correspond to the supporting network and the mobile device 100. The values in Table 4 are chosen so that networks that do not support updated configurations do not necessarily need to reduce operation in EFTA (eg, legacy non-EFTA reduction values (multislot capability reduction for downlink dual carriers). Is zero). However, the values in Table 4 are provided by way of example and other implementations are possible.

As shown in Table 4, when the mobile device omits an EFTA reduction value (eg, an additional multislot capability reduction of the downlink dual carrier of the EFTA), the network returns the reduction value to the signaled multislot of the mobile device 100. It will be recognized as the value (e.g., N-2) minus the non-EFTA reduction value (e.g., the multislot capability reduction of the downlink dual carrier) from the maximum of the reception timeslot in the class. Alternatively, when the mobile device 100 can support more receive timeslots than the maximum number of receive timeslots for the signaled multislot class, the DLDC reduction signal module 148 causes the mobile device 100 to cause the mobile device 100 to support more than one timeslots. It will send the non-EFTA reduction value as 0 and set the EFTA reduction value appropriately. Based on the received value, the network will recognize the reduction value as the subtraction of the EFTA reduction value from the maximum number of reception timeslots applicable to the alternative EFTA multislot class.

6 is a flow diagram illustrating an example process for implementing the DLDC reduction signal module 150 in accordance with the method shown in Table 4. As shown in FIG. When the DLDC reduction signal module 150 determines that it is time to signal the reception timeslot capability of the mobile device 100 to the network, the flow chart of FIG. 6 shows the reception timeslot for the multislot class for which the mobile device 100 was signaled. Begin with the DLDC reduction signal module 150 determining whether to support more than the maximum number (block 602). For example, a signaled multislot class may indicate that 10 receive timeslots are supported, but a mobile device operating on a DLDC may, for example, 16 according to the maximum number of receive timeslots for an alternative EFTA multislot class. Can support two reception timeslots.

When the mobile device supports more receive timeslots than the maximum number of receive timeslots for the signaled multislot class (block 602), the DLDC reduction signal module 150 generates a non-EFTA reduction value (e.g., downlink). Set the multislot capability reduction for dual carriers to zero (block 604). DLDC reduction signal module 150 also sets the EFTA reduction value (eg, additional multislot capability reduction for downlink dual carriers of EFTA) to the required reduction value (block 606). For example, if the maximum number of receive timeslots for the alternative EFTA multislot class of mobile device 100 is 16 and the mobile device 100 can only support 12 receive timeslots, then DLDC reduction signal module 150 Will set the EFTA reduction value to 4. Control then passes to block 612, which is described below. According to the example shown, legacy network elements that do not support additional EFTA reduction values will receive a non-EFTA reduction value of zero, and thus the time for the timeslot class for which the mobile device 100 was signaled. It will determine that it can support the maximum number of slots.

When the mobile device does not support more receive timeslots than the maximum number of receive timeslots for the signaled multislot class (block 602), the DLDC reduction signal module 150 sets the non-EFTA reduction value to the required reduction. (Block 608). For example, if the mobile device can support up to seven timeslots and the maximum number of receive timeslots for the signaled multislot class is 10, DLDC reduction signal module 150 sets the non-EFTA reduction value to three. do. DLDC reduction signal module 150 also causes the EFTA reduction value to be omitted from the subsequent information element (block 610). For example, DLDC reduction signal module 150 may cause the EFTA reduction value to be omitted by not allowing the EFTA reduction value to be added to the information element. By omitting the EFTA reduction value, the amount of data that needs to be transmitted over the network can be reduced. Alternatively, any other method can be implemented that signals to the network that a non-EFTA reduction value should be used. Control then passes to block 612.

After the DLDC reduction signal module 150 determines the appropriate non-EFTA reduction value and / or the EFTA reduction value (blocks 604-606 and 608-610), the DLDC reduction signal module 150 determines the non-EFTA reduction value and the EFTA. The capability information element (eg, MS radio access capability information element) including any or both of the decrement values is sent to the network (block 612). Although the example shown illustrates only that the non-EFTA reduction value and the EFTA reduction value are included in the capability information element, any data may be included, such as, for example, the data described in 3GPP TS 24.008.

Table 5 shows an alternative to the method described in connection with Table 4. The values in Table 5 are the same as the values in Table 4 except that the mobile device 100 supports the maximum number of receive timeslots for the alternative EFTA multislot class. In this case, DLDC reduction signal module 150 may set the non-EFTA reduction value to a value intended as a "reservation for future use" and omit the EFTA reduction value. Thus, the network element supporting the enhanced indicator will recognize such a value as an indication that the mobile device 100 supports the maximum number of receive timeslots for the alternative EFTA multislot class. Alternatively, network elements that do not support enhanced indicators (e.g., legacy networks) understand the "reservation for future use" value as zero and the number of timeslots for the multislot class for the number of received timeslots. It will not decrease below the maximum number. The value "reserved for future use" can be any value recognized by the network and understood to be zero by the legacy network. For example, the value "reserved for future use" may be a bit combination 111. Thus, signaling efficiency is achieved by not requiring transmission of the EFTA reduction value when the maximum number of receive timeslots is supported. Although the "reservation for future use" value is shown as being used in one particular example, "reservation for future use" may be used in other examples.
